Are you talking about an actual USGI M14 receiver or some type of semi-auto M14 variant (ie Springfield M1a, LRB M14, Polytech, etc.)?

If it's an actual M14, then stay away from it as it is considered a machine gun and will land you in a pile of S***. If it's a re-welded semi, then again I would stay away. Many M14 gunsmiths won't touch a re-weld.

ifthe USGI M14 receiver was properly demilled, it can be legally "rewelded" into a semi-auto receiver. The full-auto portion of the receiver must be disabled/removed before the receiver is welded back together, but it can be done. Plenty of demilled full-auto receivers are legally welded back together as semi-auto recievers.

Are rewelds receivers safe to shoot?What needs to be checked out to shoot them?Any info on this will help.
Thanks in advance

Any automatic weapon receiver must be cut into three sections with a torch and at least 1/4" of the receiver must be removed on each cut. If you manage to reassemble it the full auto switch stud and the center cut out for the oprod dismount must be made inoperable. There was a guy by the name of Kelly who had a short-lived business putting M14 receivers back together that had been sheared in two only. He's in jail and all of the receivers he made have been confiscated by the ATF. There was no payment reimbursement for the receivers by Mr. Kelly who after all is in the federal hoosgow.

ATF confiscated all the MKS rewelds they could find about 10 years ago. They consider them to still be machine guns, even though all the ones I've ever seen had the offending selector-lug on the receiver removed.

Stay away from them. If it is an Mike Kelly, Sr. reweld, it is a machine-gun in the eyes of ATF. I've never, ever seen an M14 reweld that wasn't considered a MG.
